GENERAL TROUBLE SHOOTING TIPS LIFTGATE 1. This gate can run up or down crooked 1” to 1-1/2” without hurting the gate. 2. Equalizer Valve – for adjusting the up stroke only, when the gate is loaded. 3. Flow Control Valves – for controlling the down stroke only. A partially blocked flow

control valve will reduce oil flow from one side, causing the platform to become progressively unlevel as the gate is lowered. Clean or replace in sets.

4. Bent Tie Bar – how to tell if it is bent: raise the platform to the full up position (level with the truck floor). Push the down switch. If the tie bar is bent, one side will always drop quicker than the other side immediately, and that side will always lag when the gate is raised. If bent, the tie bar will need to be replaced. BEFORE ADJUSTING OR ATTEMPTING TO FIX ANY OF THE FOUR ITEMS LISTED ABOVE, CHECK THE FOLLOWING FIRST: a. Check for bent inner mast. b. Check to see if the back edge of the platform is hitting or binding against the

floor level tube. 5. Premature motor failure is almost always caused by low batteries – batteries without

the capacity to maintain the correct voltage during the operation of the gate. 6. Inadequate grounding is also a major reason for motor failure. EMERGENCY OPERATION – POWER UNIT – GRAVITY DOWN

GROUNDING RECOMMENDATION FOR TRACTOR/TRAILER

POWER UNIT(+) POSITIVE CHARGE LINE

(-) NEGATIVE CHARGE LINEBATTERIES

The MAINTENANCE MINDER 2® controller requires that a minimum of 8 volts be maintained under load in order for the FXD® power unit to operate. Utilization of a single positive cable does not provide sufficient ground. Therefore, our recommendation for grounding tractor/trailers with a FXD® gate is as follows: Two (2) cables: one (1) positive and one (1) negative, both running to the tractor batteries. NOTE: The use of a battery charger as the sole power source to operate a FXD® is unauthorized and will prevent the FXD® from working properly. The lift gate must always be operated in conjunction with at least one (1) 12-volt dual purpose heavy-duty lift gate battery. A minimum of 10.5 volts must be maintained in order for the valves to operate.

MAINTENANCE MINDER 2® OVERVIEW Power unit is equipped with the Maintenance Minder 2® Controller. It will:

Automatically keep track of maintenance intervals and warn the user when maintenance is due, based on the number of lifts.

Record low voltage occurrences. Record of high temperature faults. Record of maximum run time faults, when a single operation exceeded the maximum

continuous run time limit. Give helpful trouble-shooting information on MENU 4, “Last Lift Info”.

FAULTS CODES A decal in the power unit enclosure lists the following signal codes for these faults: 1 BEEP Service Fault (reached the number of lifts when maintenance is due) 2 BEEPS Low Voltage Fault (check battery condition and power line connections) 3 BEEPS Max. Time Fault (exceeded the maximum continuous run time allowed) 4 BEEPS High Temperature Fault (unit will not run until motor cools) All faults signals will be repeated FOUR times, except the Service Fault signal. Controller will prevent power unit from operating during the time period when a fault signal is sounding (about 5 to 10 sec.) except for the Service Fault signal. The controller is also equipped with an anti-doorbelling feature, which prevents rapid ON/OFF operation of the power unit. RESETTING after MAINTENANCE IS PERFORMED To RESET the Maintenance Minder 2® after maintenance has been performed:

1. Go to MENU 2, hit “ENTER”, and toggle down to the “Reset All Info” screen. 2. Press and hold the hidden RESET button under Maintenance Minder 2® logo at top of

faceplate. 3. Follow the instructions on the screen regarding a second button, which must be

pressed to complete the reset operation.

BLEEDING THE LIFT CYLINDERS - GRAVITY DOWN

The FXD® is shipped with the cylinders pre-filled with hydraulic fluid from the factory. The cylinders must be bled before making any other adjustments. To Bleed the Lifting Cylinder – Bottom Side: 1. Unfold and lower the platform to the full down position. CYLINDERS SHOULD BE

EXTENDED TO THEIR FULL LENGTH (GATE EXTENDED DOWN 56”) TO REMOVE AS MUCH AIR FROM THE BOTTOM SIDE OF THE CYLINDER AS POSSIBLE. DEPENDING ON THE FLOOR HEIGHT OF THE VEHICLE, IT MAY BE NECESSARY TO RAISE THE BODY OF THE VEHICLE OR LOWER THE GATE PLATFORM INTO A PIT TO ACHIEVE MAXIMUM CYLINDER EXTENSION.

2. Loosen the plugs in the back ports (ports closest to the vehicle body), but do not remove completely.

3. Activate the pump just long enough to produce an air-free stream of oil from the ports. 4. Re-tighten the plugs in the ports, lower the platform to the full down position, and check

the oil level in the reservoir tank. The oil level should be approximately 2” from top of the tank for DUAL power units.

To Bleed the Lifting Cylinders – Top Side 1. Not applicable on gravity down. NOTE: FOR GRAVITY DOWN GATES, OIL LEVEL SHOULD ALWAYS BE CHECKED WITH THE PLATFORM UNFOLDED AND ALL THE WAY DOWN.

Back Port: This port will allow air out from the lifting (bottom) side of the cylinder.

Front Port: This port will have no oil for Gravity Down gates.

TO BLEED THE POWER FOLD CYLINDER

1. Unfold and lower the platform down to the ground. 2. Loosen the hose at the cylinder but do not remove completely. 3. Activate the pump just long enough to product an air free stream of oil from the

hose. 4. Re-tighten the hose and check the oil level in the reservoir tank. Note: hold line

while tightening to ensure it does not twist. 5. Fold and unfold the platform several times. The platform should now fold and

unfold smoothly.

CHECK OIL LEVEL AFTER BLEEDING THE CYLINDER: GRAVITY DOWN GATES – Check with platform unfolded and on ground.

POWER DOWN GATES – Check with platform unfolded and up at bed height.

ADJUSTMENT OF THE EQUALIZER VALVE NOTE: Before making any adjustments, read the General Trouble Shooting Tips page to be sure this is the problem. Do NOT adjust Equalizer Valve in an attempt to compensate for a bent Tie Bar, bad roller, or other mechanical issue. Remember adjusting the equalizer valve will control the up stroke only. Locate the equalizer valve. Equalizer valve is mounted on power unit frame, behind the power unit box. Back off the lock nut on the side that is running slow (lagging) turn the adjusting screw out ¼ turn, lock nut and try. Repeat if necessary. Although this can be done with no load on the platform, it normally helps to have a light load on the platform. NOTE: Turn the adjusting screw in = decreases the flow of oil Turn the adjusting screw out = increases the flow of oil

INNER MAST WEAR PAD ADJUSTMENT If platform comes down even when UNFOLDED, but comes down crooked when FOLDED, this could indicate the Inner Mast Wear Pads need adjustment. There is a Wear Pad opposite each roller on the Inner Mast (total of four Wear Pads) FOLLOW THESE STEPS TO CHECK THE INNER MAST WEAR PAD ADJUSTMENT:

1. PLATFORM MUST BE UNFOLDED TO MEASURE WEAR PAD CLEARANCE. Unfold the platform and run lift gate UP and DOWN at least one complete trip to assure rollers are seated in their track. Rollers must be completely seated in order to obtain a correct measurement at each Wear Pad.

2. Measure Wear Pad clearance at each location (total of 4 Wear Pads) with the platform unfolded in three (3) different positions – all the way up, in a middle position, and all the way down on the ground. You will have a total of 12 Wear Pad clearance measurements – three for each Wear Pad. Write the readings down for easy reference.

3. Refer to the diagram on the following page, and take clearance measurements at each Wear Pad using a Feeler Gauge. As an example, the top Wear Pad on the curb side might have clearance measurements of 0.080” (gate in top position), 0.092” (middle position), and 0.100” (gate at ground). Slotted Shim AP-999-214 is 0.060” thick, so one more shim can be added, since all three readings for this Wear Pad exceed 0.060”. If any of the three measurements were near 0.060” or less, then no shims could be added.

4. To add shims, loosen the 3/8-16 Hex Head Cap Screws using a 9/16 open end wrench. Insert additional shims, then tighten 3/8-16 screws. The objective is to shim each Wear Pad as close as possible, without the Wear Pad touching the track at any position (top, middle, or ground position).

5. After shim adjustments are complete at all four Wear Pad locations, run platform UP and DOWN unfolded to verify correct operation. Then fold platform and run gate UP and DOWN folded to verify correct operation.
